I have a 2000 F-250 Super Cab Lariat with the 40/20/40 bench seat in the front. I am wanting to add a subwoofer for a little more bass, mainly to take pressure off the speakers. I have been looking at Kicker, Alpine, and Cerwin Vega as they make compact sub/amp combo boxes meant to fit under seats. Usually they go under either the driver or passenger seat, but I am wondering if I can fit it in between the front center seat and the transmission tunnel hump. These boxes are only about 3 inches tall and meant to slide in tight spots like this. Has anybody done this or seen it done before? This would be the best scenario if it is possible. These boxes are ready to wire and use for only about $250.
